Application ined- September 23,1926 seria noql'srgzse I 1 'Thisinvention' relates to tools; for inserting and-removing bearing sleeves wind bearings and more particularly to an improvement on the -structure shown m my prior application,

Serial No. 107,194, filed May 6, 1926, and ellowed August '4, 1926,, for tools *forinserting and removingbearing sleeves; important 1 obj eot i of the invention is :to provide a device of t'h-is character {hav ng means forengaging and holding a split hearing sfleevewhile inserting and removing the sameto -or drom the "housing in which it is dis osed.- A

Fig. '4 is a fragmentarysectionel vieW showing the tool as applied toremove a bearing'froin its sleeve; and I I QF'i'g.v 5 is 'a side elevation' of 'a modified form of tool; I Referring now-more particularly to the drawings the numerals 10 and "11 generally designate the side "members of the tool, each including a shank '12 having at one end i thereof an arcuately "curved :portion 13 arranged in thewseiniegeneral plane as the shank end at the opposite end thereof an ercuatel-y curved porti'on l4 arranged'in a plan'e a-t rightengles'to-the shank; The ends bearingtheercuatelycurved portions 13 are pivotally ton-nected t0:'0I1e 'anQtlierat one end or the other of such srcu'ately curved portions.- 7 I y In Figure 1 the pivot 15 is located at the inner ends or theercuat'ely curved portions 13 so that a pincer likestructure is provided whilein Figure 5 the piv ot 15 lies at the outer ends of -the arcuately curved portions end s tong structure provided. Adjacent the inner ends of'the drcuately curvedportions the "shanks 121mm openings'flo for ment combine to provide a circularopening of less diameter th'en' 'the externzil" diameteror thes'leeve'S with which the deviceis to be employed. {These 'noses ma "further" be employed to cla np upon a ,c'otter pin or the like-so 'tli'zitthe structure may 'be used to withdrayvthe seine. The arcuately curved iportions l lflare externally curved upon a radius equal-to theinternel radius of the sleeve kivhen inapplied position. P'Ihe noses 2050f the arcuately-curved portions 13,hoW- ever," -co1n e =1nto *contzict "with one another before the diametrically opposed portions of the ercuately curved sections 14 are; spaced eparte distance equzilf'to the internal'di- "ameter er ithewslee've in applied position so I that it"is necessary to'flex the'sha nks 12'21ndf in'even't the spring 19 is providedyto close "theseshanks againstthe springibefore these sections maylhe inserted .Within the sleeve.

Each-of the sections '14 is slightly less in Ill semi-circle so that the necessary constriction thereof may be had. Each section has projecting from its inner edge a longitudinally extending flange 21, the free edge of which has an outturned rim The flange 21 has an external diameter equal to the internal diameter of the bearing frame 23 at the end flange 2% thereof so that by proper compression of the shanks 12, the rims 22 may be inserted through the inner end of the bearing and will, when the shanks are released, engage against the inner face of the flange 2 1 to permit the bearing to be withdrawn. As is well known to those familiar with the art, the sleeves S employed with these hearings are longitudinally split to render the same compressible and to assist in withdrawing the same have an opening 25 formed in the all thereof for reception of an implement. I accordingly provide one of the shanks 12 with an outwardly extending lug 26 which may engage in the opening 25 and be held therein by the resiliency of the arms and by spring 19 so that a pull combined with a rotative movement applied through bar 17 may be exercised to withdraw the sleeve. In order to assist in aligning the lug 9 6 with the opening 25 the outer face of one or both shanks 12 has an outstanding lug 27 for engagement against the end of the bearing sleeve S when the lug 26 is alined with this opening.

It will be obvious that the structure hereinhefore set forth may be readily and cheaply and at the same time durahly constructed and will greatly facilitate the work of removing bearings and sleeves from the housings thereof. It will also be obvious that this structure is capable of a certain range of change and modification without departing from the spirit of the invention and, therefore, I do not wish to limit myself to such specific structure except as hereinafter claimed.

I claim 1. A tool for inserting and removing bushings comprising a pair of arms connected at one end and resiliently urged apart at their opposite ends, the free end of one arm being provided with a lug for engagement in an opening in the bushing, the free ends of said arms being complementary to provide a substantially circular element adapted to engage within the bushing, said arms being provided at the opposite ends thereof with arcuately curved portions adapted to receive therebetween a bushing of the type with which the tool is to be employed and to compress the same to a diameter less than the internal diameter of the housing in which the bushing is to be inserted, said arcuately curved portions having nose portions engaging to limit movement of the free ends of the arms toward one another while the free ends of said arms are still spaced apart a distance greater than the internal diameter of the bushing with which the tool is to be employed.

A tool for inserting and removing roller bearings and the bushings thereof comprising a pair of arms connected at one end and resiliently urged apart at their opposite ends, the free end of one arm being provided with a lug for engagement in an opening in the bushing, the free ends of the arms being complementary to provide a substantially circular element to engage within and interiorly lit the bushing, and extensions on said arms providing a circular portion adapted to enter the end of the bearing and having an outturned flange for engagement with the bearing.

8. A tool for inserting and removing bushings comprising a pair of arms pivotally connected at one end and resiliently urged apart at their opposite ends, the last named ends of the arms being each provided with an arcuate extension disposed at substantially right angles to the arm, said arcuate extensions combining in one position of the arms to provide a substantially circular element adapted to engage within and interiorly it the bushing, the opposite ends of the arms having portions engaging prior to the constriction of the ends of the arms a distance sufficientto permit said circular portions to engage within the bushing whereby the resiliency of said arms opposes movement of the arms toward one another which will permit withdrawal of the circular element from the bushing.

a. A tool for inserting and removing bushings comprising a pair of arms connected at one end and resiliently urged apart at their opposite ends, the free end of one arm being provided with lug for engagement in an opening in the bushing, the free ends of said arms being complementary to arovide a substantially circular element at apted to an gage within the bushing, said arms being provided with opposed arcuately bowed portions adapted to receive therebetween a bushing of the type with which the tool is employed when the free ends of the arms are separated to the greatest extent.

5. A tool for inserting and removing bushin comprising a pair of plier connected elements the handle portions of which at the free ends thereof are complementary to provide a substantially circular element adapt ed to engage within the bushing, the jaw portions of the elements engaging while the free ends of the handle portions are still spaced apart a distance greater than the internal diameter of the bushing, one of said handle portions having a lug for engagement in an opening in the wall of the bushin 6. A tool for inserting and removing roller bearings from the bushing thereof comprising plicr connected members, the handle porl li tions of said members each having at the free end thereof an arcuate extenslon, said flange for engagement with the bearing, thejaw portions of said members having engagement with one another while the outer edges of said flanges are spaced apart a distance greater than the diameter of the opening in 10 the bearing into which they must be ex-' tended.

In testimony whereof I hereunto aflix my signature.
